[BLAQmx]

I think you made a typo in your comments. The one says it has one writer and multiple readers, but it actually has one reader, and multiple writers

I'll double check and repost the screenshot. Thanks!

In your example you have variables with "X" and "Y" in them all i get are "?"s how did you rename the variable.
BLAQmx where do you find the boolean, string, and numeric all i can find are local, global, and shared and how do you name them.
